Bollywood actor and adult-entertainment star Sunny Leone has appeared in a new ad for People for the Ethical Treatment of Animals (PETA) India.

Leone - who was named 2003 Penthouse Pet Owner of the Year - says she wants her fans to know that the only way to fight the worldwide animal homelessness crisis is always to have companion animals sterilised.

In an interview for PETA India, Leone - who shares her home in Los Angeles with two rescued dogs - said: "I believe in not buying - and adopting. And it's because there's so many dogs out there that need a home, that were left on the streets... They just need that love, and if you can rescue an animal, then that's one of the greatest gifts you can give somebody."

The actress is featured next to a caption which reads: "Too Much Sex Can Be a Bad Thing. Sterilise Your Dogs and Cats."

The Jism 2 star went on to explain: "I believe that every single dog should be spayed and neutered. You don't want to continue the cycle of homeless dogs or cats. And spaying and neutering also keeps them healthy. It prevents them from having different diseases that they can get if they are not."

The makers of Jism 2 have donated the film's wardrobe, including lingerie worn by Leone, to PETA India for auction.
